Abstract
The utility model relates to a rubber ball pump. The rubber ball pump is a back drawing type structure formed by the sequential connection of a back open type volute pump case, a back cover, a bearing chamber and a motor into integration. A pump shaft is orderly provided with a rolling bearing, a frame oil seal, a mechanical seal and an impeller and is tightly fixed by a purpose-made spherical head socket head screw; a shaft of the motor is inserted into a shaft hole of the rubber ball pump for key-type connection. The rubber ball pump can be used in rubber ball cleaning devices of a steam condenser of various capacity under 800 MW.
Description
The utility model relates in the firepower electrical plant ball cleaning apparatus of condenser, is used for carrying the centrifugal special-purpose water pump of glueballs.
The employed Rubber ball pump in existing power station all adopts pump case and impeller that broad runner is all arranged, and has and does not stop up and do not cut the characteristics of decreasing glueballs.According to the capacity difference of Turbo-generator Set, the Rubber ball pump performance of use is different (flow, lift) also.The shape of these Rubber ball pump structural types and each part is all identical, but size is different, and this just causes the Rubber ball pump model various in style, and the power industry standard DT/T581-95 of the People's Republic of China (PRC) is seen in the also more outmoded inconvenient Maintenance and Repair of structure.The 4th 235 pages of " ball cleaning apparatus of condenser and circulating water secondary filter " and " thermal power plant Hardware Description Manuals ".
The purpose of this utility model provides a kind of novel Rubber ball pump just can satisfy the following various capacity Turbo-generator Set of 800MW to the Rubber ball pump performance demands, and this pump adopts the advanced configuration of back-drawing.
The purpose of this utility model be achieved in that with bolt will back open type volute pump case, bonnet, bearing chamber and the motor all-in-one-piece back-drawing structure that is linked in sequence, order is equipped with rolling bearing on pump shaft, outside framework oil seal, mechanical seal rotatable parts and impeller, and it is fastening with special cup head socket head screw, bonnet is to be positioned on the end face of bearing chamber with screw, and be clamped between pump case and the bearing chamber, the mechanical seal static part is housed in the bonnet, and motor shaft inserts in the pump shaft hole and connects with key.The impeller of Rubber ball pump can be equipped with the impeller of various outer diameter according to the requirement of Turbo-generator Set, and other component do not change.
The utility model is owing to adopt above-mentioned method and structure, bring simplification for the technology of making glueballs, the pump component standardization, the exchange performance improves, obtain good economic benefit, thermal power plant in the Turbo-generator Set that different capabilities is housed, only need the spare part of a pump of deposit, just can satisfy and produce the needs of safeguarding, be connected owing to adopt the back-drawing structure to insert axle with pump and motor, pump is when maintenance, do not need the movement from pipe-line system of whole Rubber ball pump to come out, only need the bolt of pump case and bearing chamber is pulled down, just can extract out and overhaul, pump case still is connected in the pipe-line system, and there is not the work of cumbersome clutch alignment, adopt mechanical seal, stop a leak, reduced the regular maintenance amount.
Following structure drawings and Examples further specify the utility model.
Accompanying drawing is vertical section structure figure of the present utility model
Rolling bearing (8) is contained on the pump shaft (9), pump shaft (9) is sealed in the bearing chamber (5), load onto outside framework oil seal (7), the bonnet (4) that a whole set of mechanical seal (12) will be housed is fixed on the bearing chamber (5) with 3 screws (17), impeller (2) adopts key (16) to connect with pump shaft (9), and fixed with special cup head socket head screw (14), with stud bolt (13) bearing chamber (5) and pump case (3) are tightened together.Inlet at pump case (3) is equipped with choma (1), and it and impeller (2) are formed seal clearance.Axle (6) and key (10) with motor (11) together inserts in the endoporus that has keyway of pump shaft (9) at last, and be with bolt (15) that motor (11) and bearing chamber (5) is fastening.The impeller of Rubber ball pump (2) is a not clogging impeller of enclosed, has only 2 blades, impeller (2), and pump case (3) and bonnet (4) portion adopt the stainless steel precision casting to form, and are applicable to the circulating water (seawater, brackish water, fresh water) of any water quality.
